The target dependency evaluation rules go out the
window when you use <antcall>.
I can't see any reason why you are using <antcall>
here anyway. Your structure is just not set up in
"the Ant way." Disregarding some of your echo
logging, redundant if you use the default logger, this
would rightly be:
<project name="Test" default="get">
<target name="init">
<echo message="init called" />
</target>
<target name="getAgain" depends="init,getThird" />
<target name="getThird" depends="init">
<echo message="getThird" />
</target>
<target name="get" depends="init,getAgain" />
</project>
Obviously this was a contrived example to begin with;
feel free to post something closer to a "real build"
if you need help grasping the "Ant way."
